Abstract
Substantial effort has been invested in generating narrow bandwidth visible colors from metasurfaces using a wide variety of geometries and materials. In this work we continue these explorations and demonstrate how a combination of a plasmonic Fano resonance and a Bragg reflector can contribute to the generation of narrowband visible colors. We demonstrate active tuning of these colors by stretching the array in the x- and y- directions and the reflector in z- to shift the colorimetric response of both elements. The combination of these two types of photonic structures allows for substantially increased flexibility in design and color-space tuning. Additionally, by fabricating these structures at scale, this methodology could prove useful towards the manufacture of agile metasurface color pixels
